Hrm this would be an issue that occured when the map was made.The room won't be parsed again (for prop placement) until a new tile is added or an existing tile is sold.So the question here is not "Why has this tavern a missing table?" but "How was this tavern without table created with the map editor?"

i can confirm that the table is missing, and in addtion i can confirm that the table exists on the original version of this map stored on my PC, so something muste have gone wrong when Nano implemented it to the Game.
